“…Subduction initiation (SI) is key to study the evolution of the solid Earth and has profound implications for plate motion (Arculus et al., 2015; Crameri et al., 2020; Gerya et al., 2015; Lallemand & Arcay, 2021; Maunder et al., 2020; Niu, 2016; Stern & Gerya, 2018; Sutherland et al., 2020). Recent researches propose that there are two types of subduction initiation: vertically forced and horizontally forced SI (Crameri et al., 2020; Lallemand & Arcay, 2021).…”

“…The prerequisite for subduction initiation is the presence of density contrast not only for spontaneous but induced types of subduction initiation (Niu, 2016; Niu, O'Hara, & Pearce, 2003; Stern, 2004). Even though it is hard for subduction to initiate in the Atlantic‐type passive margins due to the presence of old and strong oceanic lithosphere, numerical modelling carried out by Zhong & Li (2020) suggested that collision will facilitate subduction initiation in the outside passive margins, and occurred repeatedly during the evolution of Tethyan systems.…”

The Kelameili Ocean was one branch of the Palaeo‐Asian Ocean, the initiation and closure history of which remains elusive. Consequently, they hamper our understanding of the accretionary evolution of the southern Altaids. In this paper, we carried out field mapping and also geochronological and geochemical analyses on the Huangcaopo Group in the northern Harlik Mountains, NW China. Field investigation revealed that “block‐in‐matrix” structure develops with blocks of andesite, limestone, sandstone, and gabbro in matrices of turbidites. Combined with our recent work, our field investigation indicates that the Huangcaopo Group is the southern extension of the Kelameili accretionary complex. A gabbro block (19HAM057) was dated at 500 ± 4 Ma, its geochemical affinity was defined to be similar to arc magmatic rocks. Magmatisms represented by two gabbroic intrusions (19HAM057‐2 and 19HAM048) were dated at the latest Devonian (360 ± 5 Ma) and the latest Carboniferous (299 ± 4 Ma), respectively. Their geochemistry displays enrichments in light rare earth elements (LREE) and large ion lithophile elements (LILE), but depletions in high field strength elements (HFSE, especially Nb and Ta). And a younger gabbroic intrusion (19HAM052) yielded crystallization age of the latest Permian (254 ± 3 Ma), and its geochemistry also shows affinity to arc magmatism. The magmatism represented by the gabbro block (19HAM057) was coeval with the Zhaheba‐Aermantai ophiolite, indicating that it was the product of incipient arc magmatism following subduction initiation in the Kelameili branch of the Palaeo‐Asian Ocean. However, two episodes of gabbroic magmas (19HAM057‐2 and 19HAM048) that intruded the Kelameili accretionary complex from the latest Devonian to latest Carboniferous indicate southward rollback of the subducting Kelameili oceanic lithosphere and resulted in the development of a growing arc. Meanwhile, the youngest gabbroic intrusion (19HAM052) suggests that northward subduction of the Kelameili oceanic lithosphere may have at least lasted to the latest Permian, indicating that the closure of the Kelameili Ocean might have been later than the latest Permian, most likely in the early Triassic. Our new data provide further constraints on the initiation and closure history of the Kelameili Ocean, which shed light on the accretionary evolution of the Altaids.

Comparative geodynamics of Aleutian and Izu-Bonin-Mariana island-arc systems

et al. 2019

Fulfilled comparative analysis of the Aleutian and Izu-Bonin-Marian island-arc systems structure and geodynamic development. Izu-Bonin-Maian island-arc systems situated along сontinental margin of Eurasia in the West of Pacific Ocean. The Aleutian island-arc system is situated between the North American and Eurasian continents. Aleutian and Izu-Bonin-Marian island-arc systems appeared to be of the same age. Both island-arc systems form autonomous Philippine and Beringia small lithospheric plates. Izu-Bonin-Marianas island-arc system formed on exclusively geodynamic interaction of oceanic plate and back-arc basins, with the main role of the Pacific subduction. Aleutian system at the initial stage was formed as a result from separation of the part of Pacific Cretaceous crust by Aleutian subduction zone. The subsequent process of Aleutian system development was caused by geodynamics of movement of North American and Eurasian lithospheric plates. Pacific plate constant oblique subduction led to expansion of Aleutian island-arc system in the Western direction.
